# Assume 'myModel' is an instance of a subclass of QAbstractItemModel index = myModel.index(0, 0) # Get index for the first row, first column data = myModel.data(index) # Retrieve data at index
# Assume 'myModel' is an instance of a subclass of QAbstractItemModel index = myModel.index(0, 0) # Get index for the first row, first column myModel.setData(index, "New Value") # Set data at index to "New Value"Both of these examples utilize the PySide QtCore QModelIndex class along with other PySide classes like QAbstractItemModel. In terms of package library, the PySide library is a Python package that provides bindings for the Qt application framework. Specifically, PySide is a package that provides Python bindings for the QtCore, QtGui, and QtWidgets modules of the Qt framework.
